Our History

With a long history in trading gasoline components, New Stone Ltd. changed in the year 2001 its focus and became active as a broking company of gasoline components and petrochemical products.
From our Swiss based office, just outside the city of Zug, a small team of well skilled professionals are serving our list of international customers, consisting of all major refineries, gasoline blenders and trading companies around the globe.

After eight years of successful operation out of our Swiss office, New Stone decided to expand their activities into other parts of the world. As of October 2009 New Stone started up brokerage services from our new office in Singapore.
The range of products consists of all gasoline blending components, Methanol and Bio-fuels.
In 2013 New Stone Broking Ltd was founded. This in order to divide all other activities and have the broking separately.

In response to the fast changing technological developments we started in 2014 the development of an online trading platform. This resulted in the founding of New Stone Technology Ltd.in November 2014.
This unique new, modern and sophisticated way of broking will bring our customers more efficiency and the latest, fastest and best available market information.

In 2015 New Stone Technology Ltd. started a joint venture with a team of well experienced brokers in the field of different petrochemical and gasoline products. This resulted in the founding of New Stone Americas. By traditional voice brokering and using the New Stone Technology Trading Platform they will assist their US based customers and give them the possibility to trade in different parts of the world.
